Medical Treatments

• X-rays are a form of electromagnetic radiation.
• X-rays have much higher energy and much shorter wavelengths than ultraviolet light.
• X rays can penetrate the human body and produce images of structures such as bones, organs, and signs of disease and injury.

• A PET scan is an imaging test that can help reveal how your tissues and organs are functioning.
• A small amount of radioactive material is necessary to show this activity.
• The type of radioactive material and its delivery method depend on which organ or tissue is being studied.

• A SPECT scan is a type of nuclear imaging test that shows how blood flows to tissues and organs.
• Radioactive drug is injected into a vein and a scanner is used.
• Makes detailed images of areas inside the body where the radioactive material is taken up by the cells.

• Shows function and structure of cardiovascular system.
• A physician may recommend cardiac imaging to support a diagnosis.
• Bone Scanning
• "Bone scan is a specialized radiology procedure used to examine the various bones of the skeleton to identify areas of physical and chemical changes in bone" ("Bone Scan"1).
• In a bone Scan a small amount of radioactive substances is used.
• The radioactive substance is called a radionuclide and is used as a tracer and goes to spots in the tissue that are not normal

• Radiation therapy uses radiation to kill cancer cells.
• A side effect is that it can damage normal cells
• A patient may receive radiation therapy at a certain time during, before ,or after surgery depending on the type of cancer being treated
• The radiation used for cancer treatment may come from a machine or radioactive material placed in the body
